One of its leaders, Doretta Peppa, a writer who calls herself a high priestess, told the BBC the temples were built to respect the gods and now they were going to be put to their proper use.

Ms Peppa said she had been given official permission to use the temple, but there were fears that the culture ministry, which administers the site, might give way to pressure from the church.

The president of the Association of Greek Clergymen, Father Efstathios Kollas, has described the followers of the Olympic gods as a handful of miserable resuscitators of a degenerate dead religion who wish to return to the monstrous dark delusions of the past.

Ms Peppa and her followers aspire to have the rights afforded to Britain's druids who worship at Stonehenge, and Danish believers in Thor and the Nordic gods who are allowed to perform marriages, baptisms and funerals.
